Wind got a little high about half way through A-half, but it never got over 30mph. Problem initializing the support library on ARCSAT around 00:30. Rebooting the software seemed to fix it. Problem clamping when we had to rotate the tertiary from NA1 to NA2. Error messages below. We had to go into talk2boxes and set the rotator position manually. 2024-10-07 07:10:19 .telmech.0 0 telmech w RawLine="?LMSTOP clamp failed to fully close\"" The night was overall fairly uneventful, and weather was nice and clear! There was some really nice zodiacal light on the all sky cam this morning! ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:26 ecamera 492( 409) 22 58 12.9 13.1 13.9 12.8 12.8 ND2 0.81 20:10 ecamera 422( 308) 1 59 12.6 12.4 13.3 12.2 12.3 clear 1.17 23:45 ecamera 362( 170) -62 30 10.6 10.3 11.1 10.2 10.3 clear 1.99 01:27 tcamera 338( 1365) 89 48 10.5 10.0 10.5 10.0 10.4 -- 2.02 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 62 20 12 91 (E) 970 mstly clr none 17:00 61 18 10 86 (E) 944 mstly clr none 18:00 59 27 18 78 (ENE) 1177 clear none 19:00 56 30 20 81 (E) 1270 clear none 20:00 55 32 23 83 (E) 1497 clear none 21:00 54 31 14 62 (ENE) 1486 clear none 22:00 53 27 24 76 (ENE) 1148 clear none 23:00 52 31 26 74 (ENE) 1109 clear none 00:00 51 32 25 70 (ENE) 1142 clear none 01:00 50 32 26 74 (ENE) 1070 clear none 02:00 51 32 20 74 (ENE) 1177 clear none 03:00 51 31 24 72 (ENE) 977 clear none 04:00 50 32 24 67 (ENE) 1108 clear none 05:00 50 32 16 79 (E) 1117 clear none 06:00 49 32 18 73 (ENE) 1204 clear none Note: the wind was coming from the azimuth listed.
